LOUIS EMILE ANDRE GILLIER, OF TROYES, FRANCE.

VAPORIZINGI3EV ICE FOR WEAVING APPARATUS.

To all whom it may concern:

Be it known that I, LOUIS EMILE Armin: GILLIER, a citizen of the French Republic, residing at Troyes, France, have invented a certain new and useful vaporizing Device for Weaving Apparatus, of which the following is a specification.

This invention relates to a vaporizing device by means of which threads (more particularly silk threads) can be treated with vapor at the moment of wearing. This device is chiefly characterized by means which reducethe escape of steam from the apparatus, and also prevent the rise of temperature in the weaving room. These means chiefly bring about the condensation of the steam introduced into the chamber through which the thread passes for treatment with vapor, by utilizing for the purpose a circulation of cold water which moreover forms a non-conducting screen round said chamber. These means also render it possible to prevent the drops of water produced by the condensation of the steam, from reaching.

the thread.

The vaporizing chamber through which the thread passes and into which steam is admitted, is arranged in an expansion and condensation inclosure with which it is in open communication. This inclosure is formed by a double wall which surrounds and surmounts the vaporizing chamber and is fed through the top. The inner walls of the inclosure are in contact with the refrigerating chamber, so that water trickles on the said walls and is collected at the lower portion of the said inclosure from which it is subsequently discharged. The threads, in order to net into the inner vaporizing chamber, pass through small orifices made in the outer wall of the water circulation chamber and pass through large passages which are in the latter chamber. The water cooled walls of the said passages produce a suflicient fall of temperature for considerably reducing the passage of steam through the inlet and outlet orifices for the thread. In the interior of the condensation inclosure, these passages are extended, and in combination with the roof on the vaporizing chamber, prevent the drops of con: densed water from falling on the thread during its passage.

Specification of Letters Patent.

Serial No. 787,699.

In the construction described by way of example, the water circulation chamber surrounding the vaporizing chamber, is formed by two arallel vertical walls on which a hollow cover is placed which does not close the said chamber, but forms a supply tank. Pipes passing through the refrigerating chamber, are closed outside by a cover provided with a central opening for the passage of the thread, and are beveled inside and project under the caves of the aforesaid roof on the vaporizing chamber. The vaporizing and condensation chambers are in communication with the outside by means of water discharge pipes provided on their respective bottoms. The inner walls of the circulation chamber constitutes a condenser, and water trickles down them from openings provided near the top.

A construction according to this invention is shown, in which- Figure 1 is a cross-section, and Fig. 2 is ranged surmounted by a sloped roof h and supported above the bottom of the casing a, on distance pieces z' through which can pass water branches 7' or steam branches is. The inner chamber 9 is provided with large openings Z opposite the pipes b. Collector gutters m are arranged on the edges connecting the vertical walls of the vaporizing chamber with the slopes h. The chamber g has a water discharge pipe j which opens at a certain distance above its bottom, and a steam supply pipe or pipes 70, the axis or axes of which are respectively arranged in a vertical plane containing the orifices f. The steam supply pipes 73 are covered respectively by a cap n. in the lateral wall of which inlet openings 0 are provided.

The inclosure 0 is closed by a hollow cover p, the flange (7 of which projects downward so as to dip into the chamber, in which the water circulates: This chamber communicates with the inclosure c by means of orifices 1" provided in the upper portion of the inner walls and is supplied with water from a feed pipe 23 by means of conduits s passing through the flange of the hollow cover 39. lwforeover, the inclosure 0 is placed in communication with the atmosphere by means of a pipe 26, the orifice of which is situated at a certain level above the bottom.

The thread or threads which pass into the vaporizing chamber 9 along the line ma through the orifices f are exposed to the action of low pressure steam (about 200 gr. above atmospheric pressure) supplied through the pipes 73 filling the said chamber.

Steam passes from the chamber 9 through the openings Z into the expansion and condensing chamber 0. The water supplied to the hollow cover 79, forms a cooling layer, the level of which is determined by the position of the orifices 8 through which water passes into the chamber a, and circulates owing to difierences of density. Water rendered luke-warm by its contact with the inner wall of the chamber, rises and passes through the holes 7' into the steam expansion and condensing chamber a. It trickles on the wall, collects at the bottom and is discharged through the pipe 24. Nevertheless there is left on the bottom a layer of water, the level of which is limited by the height of the orifice of the pipe 24 from the bottom.

The steam which was contained in the inclosure 0, is condensed by its contact with the cold walls of the chamber a, and by mixing with the cold water trickling along the said walls. The products of condensation which are also flowing on the slopes 7 of the roof, are discharged through the pipe at with the water coming from the cooling chamber a.

The water produced by the partial con densation of steam in the vaporizing chamber g, is discharged through the pipe j. It will be seen that the thread is protected from the falling of drops of water by the pipes b and by the slopes 7b as well as by the inner drip pipes or gutters m.

It will be readily understood that the chamber a in which water circulates, constitutes a non-conducting casing which opposes any thermic exchange by radiation or convection between the chamber 9 receiving steam for the treatment of the thread, and the surrounding atmosphere.

Owing to the condensation of steam and to the cooling of the pipes Z9 through which the threads pass (these pipes 6 being embedded in the non-conducting chamber a), the escape of steam through the holes f is reduced. At the upper portion, the escape of the steam contained in the chamber 0, is prevented by the flange q of the cover p, which by dipping into the circulation chamher a, constitutes a hydraulic seal.
